GM warning 800,000 owners that their cars may need oil changes more frequently than they say

The days of changing your engine oil every 3,000 miles are long gone thanks to most cars having automatic oil monitoring systems, but about 800,000 General Motors vehicles apparently have incorrect monitoring software that is leading to premature engine component wear. According to Autoweek, certain 2010-2012 Buick LaCrosse, Regal, Chevrolet Equinox and GMC Terrain models equipped with 2.4-liter four-cylinder engines could be going too long in between oil changes resulting in a higher-than-normal number of warranty claims for the engine's balance chain. The balance chain links the balance shaft to the crankshaft, and a worn one can produce higher noise levels.
As a fix, GM dealers will be reprogramming the software for the monitors in an effort to reduce the interval between oil changes, which varies based on driving habits and conditions. Through February 2015, the software update will be done at no cost to vehicle owners, but since this is not a recall, after that point, it will be up to the discretion of dealers as to whether or not they will charge for the service. What isn't immediately clear is whether GM plans on giving assistance to out-of-warranty customers who are experiencing engine issues from the worn chain.

Buick Encore blitzes first-year sales predictions

With its first full year of sales in the bag, it's safe to say that Buick has a hit on its hands with the Encore. US buyers have snatched up 31,046 of the small, premium crossovers since the Encore went on sale in January of 2013, while 97,311 were sold globally (not counting its counterparts from Opel and Vauxhall).
While we liked the Encore when we first drove it, we'll admit, we weren't sure how the tiny CUV would do. In fact, the first thing Executive Editor Chris Paukert wrote about the Encore was, "We admit it. We have no earthly idea how this whole thing is going to shake out." But it's done well, and has been subject to heavy demand over the past year, blowing away the estimates of analysts, who, according to an August story from Automotive News, projected no more than 18,500 units would be sold in 2013.
"Right out of the gate, demand for the Encore was high," Tony DiSalle, vice president of Buick marketing said in a statement. "It accounted for most of the segment's growth last year and that's because it offers the right safety, technology and features in the right-sized vehicle for many customers."

GM announces 6 recalls covering nearly 720k cars

General Motors has announced yet another sprawling recall campaign, with six separate elements covering 717,950 vehicles on US roads. At this point in 2014, it's starting to seem like there are more days with a GM recall than without. Perhaps most troubling about this latest volley, though, is that every vehicle is from the past few years, indicating that GM's quality woes may not be limited to pre-bankruptcy vehicles.
The largest element of this latest campaign covers 414,333 units, and includes the 2011 to 2012 Chevrolet Camaro, 2010 to 2012 Chevy Equinox, GMC Terrain and Cadillac SRX and the 2011 to 2012 Buick Regal and LaCrosse. Only vehicles with powered, height-adjustable seats are covered. In these particular cars and crossovers, the bolt that secures the height adjuster actuator may loosen of its own accord and in some cases fall out completely. If this happens, the seats will be able to move both up and down. GM claims the vehicles are safe to drive, provided drivers don't vertically adjust their seats. This particular issue has caused one crash and three injuries.
